        <p>
            Executes an HTTP request to your specified URL when a check
            goes up or down.  You can use placeholders <strong>$NAME</strong>,
            <strong>$STATUS</strong> and others in webhook URLs, request body and

            Webhook retry policy:
            {% site_name %} retries failed webhook calls up to 2 additional times.
            {% site_name %} considers a HTTP request failed if:

            <li>The destination server does not return a complete response within 30 seconds.</li>
            <li>The HTTP response status code is not one of: 200, 201, 202 or 204.</li>
